Sure thing, let's get straight to it. We start with 438 and we're going to multiply it by 39, which means adding 438 to itself 39 times.
Step 1: 0 + 438 = 438
Step 2: 438 + 438 = 876
Step 3: 876 + 438 = 1314
Step 4: 1314 + 438 = 1752
Step 5: 1752 + 438 = 2190
Step 6: 2190 + 438 = 2628
Step 7: 2628 + 438 = 3066
Step 8: 3066 + 438 = 3504
Step 9: 3504 + 438 = 3942
Step 10: 3942 + 438 = 4380
Step 11: 4380 + 438 = 4818
Step 12: 4818 + 438 = 5256
Step 13: 5256 + 438 = 5694
Step 14: 5694 + 438 = 6132
Step 15: 6132 + 438 = 6570
Step 16: 6570 + 438 = 7008
Step 17: 7008 + 438 = 7446
Step 18: 7446 + 438 = 7884
Step 19: 7884 + 438 = 8322
Step 20: 8322 + 438 = 8760
Step 21: 8760 + 438 = 9198
Step 22: 9198 + 438 = 9636
Step 23: 9636 + 438 = 10074
Step 24: 10074 + 438 = 10512
Step 25: 10512 + 438 = 10950
Step 26: 10950 + 438 = 11388
Step 27: 11388 + 438 = 11826
Step 28: 11826 + 438 = 12264
Step 29: 12264 + 438 = 12702
Step 30: 12702 + 438 = 13140
Step 31: 13140 + 438 = 13578
Step 32: 13578 + 438 = 14016
Step 33: 14016 + 438 = 14454
Step 34: 14454 + 438 = 14892
Step 35: 14892 + 438 = 15330
Step 36: 15330 + 438 = 15768
Step 37: 15768 + 438 = 16206
Step 38: 16206 + 438 = 16644
Step 39: 16644 + 438 = 17082

So, 438*39 = 17082
